Question: What is the area of a sector of a circle with a radius of 5 cm and a central angle of 60 degrees? (Use π = 3.14)

Options:

Correct Answer: 13.09 cm²

Solution:

Area of sector = (θ/360) × πr² = (60/360) × 3.14 × (5 cm)² = 13.09 cm².

What is the area of a sector of a circle with a radius of 5 cm and a central angle of 60 degrees? (Use π = 3.14)

Correct Answer: 13.09 cm²

Step 1: Identify the radius of the circle, which is given as 5 cm.
Step 2: Identify the central angle of the sector, which is given as 60 degrees.
Step 3: Use the formula for the area of a sector: Area = (θ/360) × πr².
Step 4: Substitute the values into the formula: Area = (60/360) × 3.14 × (5 cm)².
Step 5: Calculate (5 cm)², which is 25 cm².
Step 6: Now substitute this value back into the formula: Area = (60/360) × 3.14 × 25 cm².
Step 7: Simplify (60/360) to 1/6.
Step 8: Now calculate the area: Area = (1/6) × 3.14 × 25 cm².
Step 9: Multiply 3.14 by 25, which equals 78.5.
Step 10: Now divide 78.5 by 6 to find the area: Area = 78.5 / 6 = 13.09 cm².
